To aZZ whom it may concem.'

Be it'known that I, VINCENT CALABRESE, a

' citizen of the United States, and a resident tains more particularly to the film-wi Ves of the city of New York, borough of Brooklyn, in the vcounty of Kings and State of New York, 'have invented a new and Improved Camera, of which the following is a full, clear, and exact descri tion.

The present invention re atesto new and useful improvements in cameras, andit er- 1n mechanism thereof. g

It is one of the primary objects/...of the present invention to provide a filmfwinding mechanism which is so constructed that when desired the film spool may-be operated `to position an unexposed section of the film strip behind the shutter-opening after the operation of the shutter.

It is a furthelfobject of the present invention to provide means whereby an automatic winding of the film to properly position the various sections thereof behind the shutter opening, is obtained.

1t is a still further object kof the invention toso construct the .device that the paper strip on which the film is carried will be wound upon the winding spool both before the first exposure and after the last exposure in order that the spool maybe removed from the camera without injurylor danger of ex posure of any section of the film strip.

With theabove and other objects in view, reference is had .to the accompanying drawings, in which-` a Figure 1 is a transverse sectional view of a camera constructed in accordance with the present invention; l

Fig. 2 is a sectional view taken on the line 2 2 of Fig. 3;

Fig. 3 is a rear end elevation tion and partly broken away; l

Fig. 4 is a view of the shutter mechanism showing in dotted lines, the several positions ofpits mechanism durin the different steps in the operation thereo f `Referring more particularly to the drawings, the reference character' 5 designates 'a camera which may be of any suitable form so lon as it is of the" film type. The reference c aracter 6 designates the yspool carrier for a spool of unexposed film, while the referencecharacter 7 designates the carrier for the spool on which the exposed film is wound.-

The reference character 10 designates a partly in secspring barrel, and formed integral with said spring barrel or secured thereto in any suitable manner to be driven thereby, is a wheel 11 .1, This gear wheel 1l is adapted to mesh on one side with a -small gear wheel 12,

which gear wheel is provided with a flange or lug 13 adapted to be received Within the slot in the end of a film spool, which latter construction, however, is not shown in the present case, since it forms no part of the present invention. g

ounted within the spring barrel is a coil spring 11 and the inner end of said coil spring 11 is secured, as at 12', to a lug 13 projecting from'the gear wheel 11. The gear wheel 13 fixed to gear wheel 11 meshes with a gear lwheel 14 mounted, as at 15, and carried by the gear wheel 14 is a notched disk 16. This disk 16 is provided with a plurality of peripheral notches 17. There are seven of these notches 17 Agrouped together and arranged in relatively close rela, tion, while intermediate of the end notches of the group, is a lnotch 18, the purpose of which will be hereinafter described.

gear

The reference characters 20, 21, 22, 23, i

- the gear 25, is a stopping mechanism 27, and

this stopping mechanism 27 consists of a disk, on the peripheral edge ofv which is provided a shoulder 28. This shoulder 28 is adapted to be engagedby means of a pawl 29. pivoted intermediate its ends as at 30, and maintained in en gement with the peripheral edge ofthe dis by means of a spring 31.

This p'awl is provided on oneof its ends with a projection 32, said proiection being carried by the end opposite to that which engages the shoulder 28, to control the movement of the train of gears heretofore mentioned.

Pivotally mounted as at 33, is a latch 34, and one end of this latch is provided with a right-angular extension 35 adapted to engage the notches of the notched disk 16.

The opposite end of this latch 34 is adapted to engage the projection 32 of the pawl` 29, as indicated by the /reference character 36. The pivot 33 of the latc'h 34 extends through the plate 40, on which the foregoing mechanism is mounted, and upon the opposite side of the plate, the pivot point of sald latch is o' gage the lever 5l, and vvhenl said shutterprovided with a lever 41. This .pivot 33 of the latch 34 is rigidly secured `to the lever intermediate of its'ends in such a 'manner that projecting'in opposite directions from the pivot point 33 are arms 42 and 43. Pivotally mounted, asat v44, "is a lever 45, the

pivotal mounting 44 being between the endsI of the lever.- One of the e ds of the .lever 45 is formed with a right-angular extension opposite end 51 of this lever 49 is adapted to occupy a position in which it is parallel with the lever 47, and v1s spaced with relation thereto. Each of these levers and 49 is limited in its movement in one'direction by means of a suitable stop ,52.

Projecting through an open1ng53 1n one of the walls ofthe camera, is a rigid member 54 and said member is rigidly secured as at 55, to the shutter-operating lever This shutter-operating lever 56 is pivotally mountedas at 57, and has its operating end 58 projected beyond one wall of the camera through an opening 59 formed therein. A spring 59 is employed to return the lever 58 to normal position yafter each operation thereof. The shutter is designated by the reference character 60, and said shutter is provided with an exposure openingA 61 adapted to move by the lens 62 in order to permit of a projection of the light therethrough. 'As shown in Fig. 4, the heavy dot-and-dash line A and the heavy dotted line B, this shutter-operating leyer56 is capable of-a movement beyond the point nec-r essary to opera-te the shutter, the movement necessary to operate the'shutter being indicated by the full-line position of the lever and the light dot-and-dash line C in said vligure. As this shutter-operating lever vis moved from the position shown in full lines to the position designated by the reference charact'er'A, the rigid member 54 will enoperatng lever 56'is moved from the position C tothe position B, said rigid Vmember 54 will engage the end 47 of the pivoted lever45.r f' Y --Secured to the opposite side of the plate 40 to'that onl which the train of gearing. is

' secured, is a gear Wheel 60, and meshing with said gear Wheel 60,^is a gear Wheel 61. This gear Wheel 61 i's'rigidly carried by a shaft 62 which projects through one of thewalls ofthe camera, and is provided With movement of the gear wheel 60, is a Apawl 65, which is maintained in engagement with the teeth of the circular rack 64, by Vmeans .of a spring 66.

The device operates in the following manner: Y

. Assumin that a new roll of vilm hasbeen placed in t e carrier 6 and the free end of this action will` move the rigid member 54 intoengagement with the'end 51of the pivoted lever 49 and rock said' lever about its pivot. The lever' in rocking about its pivot will engage the arm 43 of the lever 41, and

This rocking of the shaft 33 by the lever 4l,

its black paper strip is securedto the spool carried by the carrier 7, and the shutter-op-ll rock said lever about its pivotal point 33.

lifts the pawl 29 out of engagement with the shoulder 28O of the cam 27, and. permits of an operation of the train of gears, the coil 11 actingas the motive force. 'i

Simultaneously with the movement of the pawl 29 out of engagement with the shoulder 28,-tl1eV dog 34 is, disengaged from the recess 18 and the notched disk 16 rotates. Upon rotation of the-notched disk 16the end 35 4ot' 'the dog- 34 engages in the next 'notch' and this engagementY 3f the rightangular end 35 'of the dog 34 with this notch y permits of the pawl29 moving to a position Where it will be engaged by the shoulder 28 of the cam 27. This movement of the notched disk will' wind enough of the black paper strip to position the :first film opposite `the shutter opening of the camera.

Assuming 3now that the s utter is operated by movement of the lever 58' to the position C in Fig. 4, to make an exposure: From the position C, the operating lever 58 is moved to the yposition BA in Fig-'4, and in its movement the rigid member 54 engages the end 47 of the pivoted lever 45 and rocks the lever 41 byreasoniof the 'engagement of the los end 46 with the arm-42 of the lever 41 to repeat the operation.

The herein described operation is carried out with each exposure except where it ma be desired to take time exposures, whic operation requires adouble operation of the shutter-operating mechanism, and t@ aceomplish this, the operator is careful not to move the shutter-operating mechanism beyond the full-line position shown in Fig. 4, when moving the same upwardly or beyond the position indicated 'by the reference char-- acter C when moved ldownwardly until after -the second operation of the shutter. Va wvindng key A63.` Carried by the rear face From the' foregoing it will be yseen that the present invention provides a mechan-ically-operated mechanism lfor winding the film spool in a camera, 'and that the same is dependent upon the shutter-operating inechanism for its operation and operated thereby.

Furthermore, in the present construction, provision is made whereby the film-Winding mechanism is not operated With each operation of the shutter-operating lever, but said shutter-operating lever may b e operated independently of the winding mechanism, if desired. @By such a construction, it will be readily apparent that with a camera so equipped, a pluralit'yrof pictures of moving ob]ects may be takenv in sequence, and deupendent upon the speed at which the train of gearing drives the film-Winding spool, these exposures in sequence may be made at varying intervals.

What is claimed is: n

l. In combination with a camera, its shutter operating mechanism, and film winding mechanism, automatic means for operating the film Winding mechanism upon excessive operation of the shutter operating mechanism.

2. In combination with the shutter actuating mechanism and film winding mechanism of a camera, mechanically operated means for operating said film Winding vmechanism and including an actuating lever movable alternately in opposite directions for actuating the shutter mechanism, and means cooperative between the lever 'and winding mechanism to release the Winding mechanism upon movement of the lever in either direction".
